IMPROVEMENT IN HIDE- SCOURING MACHINES.

Specification forming part of Letters Patent No. 170,771, dated December7, 1875 application filed To all whom itmay concern:

Be it known that I, CARL RosE, of the city of New York, county and Stateof New York, have invented an Improved Hide Scouring and CleaningMachine, of which the following is a specification Figure 1 is afrontelevation of myimproved scouring and cleaning machine. Fig. 2 is aside elevation of the same. Fig. 3 is a top view, partly in section, ofthe same. Fig. 4is a side view, and Fig. 5 an end view, of one of thescraping-rollers used on the machine. Fig. 6 is a side view, and Fig. 7an end view, of an: other style of roller used on the machine.

Similar letters of reference indicate corresponding parts in all thefigures.

This invention relates to anew machine for scouring, fleshin g, andcleaning hides preparatory and subsequent to the tanning process, forremoving impurities from the flesh side of the hides, breaking the hidesto facilitate the tanning process, removing the hair when de sired, andrubbing or pressing them after liming to express the surplus lime usedin the process of tanning.

My invention consists, principally, in the employment of a rotary bedfor the hide to be scoured or rubbed, in place of the stationary bedsheretofore used. The invention consists, also, in improvements in thearrangement of the pendulum-frame in which the scouringroller issuspended, and in an improved steel scouring-brush, all as hereinaftermore fully described.

In the accompanying drawing, the letter A represents the stationaryframe-work of the machine, ofwhich the upper part may be formed by theceiling of the room in which the machine is set up. B is a fixed table,on which the operator stands and adjusts and holds the hides. O is adrum, hung horizontally, or nearly so, directly in front of the table,so that the latter is between the drum and the operator. The drum is ofa length sufficient to receive that portion of the hides which is to beacted upon at one time, and is made of suitable material. ltscircumference may, if desired, be rendered more or less elastic by acovering of rubber or equivalent substance, or fabric. D is a pendulum-frame, suspended from a horizontal shaft, E, from the ceiling orNovember 15, 1875.

upper part of the frame A, and carrying at its lower part a shaft, F,upon which the scouring-roller G is mounted. The shaft E has its bearings in suitable brackets 11 a, and receives rotary motion by suitablemeans, and transmits its motion by a belt, I), or otherwise to the shaftF and roller G. But motion may be imparted to the shaftFotherwise thanfrom the shaft E. The axis of the shaftE is almost vertically above thatof the drum 0, as shown in Fig. 2, and the length of the frame D suchthat its weight will tend to hold the roller G in contact with the drum0. If the two are thus in contact, directly or indirectly, t. 6., with ahide intervening, the drum 0 will be turned by the roller G.

The lower part of the frame D is, by a series of jointed levers, d, e,f, and g, connected with a treadle, h, in such manner that, by steppingon said treadle, or should it be omitted, by pulling on the lever g, theroller G will be tightly drawn against the drum 0. By atogglejoint, (Zt, the frame D may also be connectedwith the frame A, as shown, but notnecessarily so, said connection being only desirable in case the frame Dis too light to remain steady.

The roller Gis for scouring ahide on the flesh side, fitted with aseries of flat steel blades or strips j j, which are preferably arrangedin tufts and set in the body of the roller, with their flat sidesparallel to the axis thereof, so as to constitute a brushing-surface,which will effectually remove the flesh and impurities from the hideWithout scratching or tearing the same, and which will also break thehide, to render it properly susceptible for the tanning process, towhich it is subsequently exposed.

For removing the hair or treating the flesh side of very fine skin, Ipropose to use a brush of whalebone or similar material, set into-theroller G, or to set rubber blades into the periphery of the roller.

For various purposes, metallic rollers of the style represented in Figs.4 and 5, or rollers with stone rubbers KK, like those represented inFigs. 6 and 7, may be placed in the frame D to act on the hide, which isplaced on the drum 0. Especially the style of roller last named will beuseful for sleeking the hide after it comes out of the vat,andexpressing the surplus lime.

, brought against it to affect it in the desired manner, the frictionalcontact with said roller serving to feed the hide on and with the drum0, which is turned by such friction in the direction of the arrowindicated in Fig. 2; For greater effect the hide may, after it has beenfed nearly past the roller G, be pulled back by the operator against thedirection of rotation of the roller, in which case the drum 0 willfollow the motion which is imparted to the hide.

' I claim as my invention- 1. The combination of the rotary bed 0, withthe pendulum-frame D and scouring-roller G, substantially as hereinshown and de-' scribed. v a

2. The pendulum-frame D, carrying the scouring-roller, and combined withthe system of levers d e f g, substantially as and for the purposeherein shown and described.

3. The rotary scouring-brush G, provided with series or tufts of elasticsheet-strips j j, set with their faces parallel to the axis of theroller, substantially as specified.
